Upon receipt of the image information, the panel drive chips 107 can form letters and images on the display panel 105. The timing controller can serve to adjust the amount of data to be transmitted to the panel drive chips 107 of the display panel 105 and to improve picture quality. The transmission of image information to the panel drive chips 107 can be achieved through chip terminals 135 disposed at the lower side of the drive board 130.
The SMPS 350 can supply power to the drive board 130 according to a control signal from the main board 360. The drive board 130 can transmit the power to the display module 103. As a result, the power can be to the light sources of the back light assembly 115. Also, the power can be supplied to the panel drive chips 107 and various other components.
Since the SMPS 350 and the main board 360 can be located in the base unit 300, the drive board 130 serves to supply power to the display module 103 in addition to functioning as the timing controller.
The base unit 300 can be positioned a first position in which the base unit 300 supports the cover unit 200 below the cover unit 200. In this case, the display apparatus 1 includes a detachable neck cover 600 to maintain the first position (see FIGS. 1 and 2).
The neck cover 600 can serve to maintain the first position while covering the connection unit 400, the cover unit 200, and the part 310 of the base unit 300. That is, the neck cover 600 can maintain the positional relations among the cover unit 200, the connection unit 400, and the base unit 300.
Hereinafter, positions of the base unit and a process of changing the positions of the base unit according to an exemplary embodiment of the present general inventive concept will be described.
FIG. 4 is a side view of the display apparatus in a state in which the base unit is located at a first position, FIG. 5 is an enlarged sectional view of the connection unit of FIG. 4, FIG. 6 is a side view illustrating a process of changing the position of the base unit from the first position to a second position, wherein the angle of rotation ⊖ of the base unit is also illustrated, FIG. 7 is a rear perspective view of the display apparatus in a state in which the base unit is located at the second position, and FIG. 8 is an enlarged sectional view of the connection unit of FIG. 7.
As illustrated in FIGS. 4 and 5, the base unit 300 can support the cover unit 200 via the connection unit 400 below the cover unit 200 when the base unit 300 is located at the first position. The neck cover 600 can maintain such a supported state.
The upper part of the neck cover 600 can couple to the rear of the cover 200 by upper fixing screws 610, and the lower part of the neck cover 600 can couple to the top of the base unit 300 by lower fixing screws 620. More specifically, the lower fixing screws 620 are connected to lower fixing screws mounting 320 of base unit 300.
The neck cover 600 can cover the connection unit 400, the cover unit 200, and the part 310 of the base unit 300. Also, the neck cover 600 can serve to decorate the rear of the display apparatus 1.
The first position may be a stand position in which the base unit 300 serves as a stand to support the display body 100.
The position of the base unit 300 can be changed from the first position to a second position as illustrated in FIGS. 7 and 8.
First, the neck cover 600 can separate from the display apparatus 1 by loosening the upper fixing screws 610 and the lower fixing screws 620.
Subsequently, the connection unit 400 can be rotatably pushed in the rear direction of the cover unit 200 such that the connection unit 400 is hingedly rotatable, and the base unit 300 is hingedly rotatable in the direction opposite to the hinged rotation direction of the connection unit 400 such that the base unit 300 comes into tight contact with the rear of the cover unit 200. That is, the connection unit 400 can fold such that the base unit 300 tightly contacts the cover unit 200.
At this time, the hinged rotation and folding of the connection unit 400 and the base unit 300 can be smoothly achieved by the first hinge 440 and the second hinge 460.
In a state in which the base unit 300 is in tight contact with the rear of the cover unit 200, the base unit 300 can fix to the cover unit 200 by screws 710 a and 710 b. More specifically, the screws 710 a and 710 b can be fixed to the cover unit 200 by inserting through the holes 310 a and 310 b.
As a result, the base unit 300 can be located at the second position in which the base unit 300 is fixed to the rear of the cover unit 200. In the second position, the bottom of the base unit 300 may be fixed to a wall, whereby the display apparatus 1 is mounted to the wall. Alternatively, the display apparatus 1 may be mounted to the wall using a wire (not illustrated). In this case, the base unit 300 can be provided at the bottom thereof with wire fixing parts. The wire can be fixed to the wire fixing parts, and the wire is hung on a wire hook formed at the wall. As a result, the display apparatus 1 is mounted to the wall. Technology for mounting the display apparatus 1 to the wall is a conventional art, and therefore, a detailed description thereof is omitted.
At the second position, the display apparatus 1 can mount to the wall through the base unit 300. At this time, the position of the base unit 300 is a wall mount position.
A minimum number of components to display pictures can be disposed in the display body 100, and other main components, such as the SMPS 350, the main board 360, and the speakers 380, can be disposed in the base unit 300. As a result, the display body 100 becomes slim.
Also, the connection unit 400 may be disposed between the display body 100 and the base unit 300 such that the base unit 300 can serve as a stand to support the display body 100 at the first position, and the display apparatus 1 can mount to the wall through the base unit 300 at the second position.
Furthermore, as illustrated in FIG. 7, ventilation slots 255 may be cut into the rear cover 240 of the cover unit 200 to facilitate with cooling of the display apparatus.
As is apparent from the above description, the number of components disposed in the display body of the display apparatus to display pictures can be minimized, thereby achieving slimness of the display body.
Also, the display apparatus can provide an aesthetically pleasing appearance through the slimness of the display body.
Although a few exemplary embodiments of the present general inventive concept have been illustrated and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the present general inventive concept, the scope of which is defined in the claims and their equivalents.
